The effect of varying molecular weights on the rate of diffusion essay

New hampshire4OH with the lower molecular weight at Potassium dichromate appeared to have a faster rate of diffusion. Instead of the Potassium permanganate, the Potassium dichromate appears to have the fastest diffusion rate of the three. Inhis work was subsequently published in the Philosophical Magazine.

Therefore a lighter gas such as H must be put in the chamber since it will supply higher values of diffusion rates. This means that the higher the molecular weight, the slower the rate of diffusion and frailty versa.

Some factors include the temperature.

The Effect of Varying Molecular Weights on the Rate of Diffusion Essay Sample

The hypothesis derived from the glass tubing set-up was so tested by the usage of the agar H2O gel set-up. One is through the use of Glass tube set up where diffusion rate was measured through the distance of white ring of smoke from hydrochloric acid HCl and ammonium hydroxide NH4OH.

Under similar conditions, oxygen diffuses faster than carbon dioxide. The H2O agar-gel apparatus was made up of a petri dish incorporating the gel with three Wellss.

These values were so plotted. The set-up included the usage of K permanganate KMnO4. This is because a bigger molecule requires greater force in able to move such particle, unlike the smaller particle which merely needs a lesser force for it to move Meyertholen, The glass tube set-up was used to prove that the molecular weight of a substance affects its rate of diffusion.

The mean rate of diffusion is still different from the partial rates of diffusion. The diameter of the wells at 0 minute to 30 minutes were then measured and recorded for every 30 minutes.

The form refering the rate of diffusion could non be precisely determined.

The Effect of Molecular Weight on the Rate of Diffusion of Substances Essay Sample

This observation showed that the hypothesis aforementioned was true because with the data given, the idea of having a molecular weight will slow down its rate of diffusion is evident. This may so function as one of the factors that affect the rate of diffusion.

Gases tend to diffuse rapidly with each other. The distances in cm form both ends of the glass tubing until the position where it was marked, were measured. Hire writer The consequence of molecular weight on the rate of diffusion was verified by the 2 trials: Potassium permanganate KMnO4holding the lowest molecular weight, presented the biggest diameter at 14 millimeter and diffused at the fastest rate at 0.

Satake also proposed that molecular weight is proportional to the rate of diffusion. K bichromate K2Cr2O7 and methylene blue that were sinked in the three Wellss in the agar-water gel.The Effect of Molecular Weights on the Rate of Diffusion Sharmaine S.

Bungabong Group 1 Sec. Y-7L August 11, A scientific paper submitted in partial fulfilment of the requirements in General Biology I Laboratory under Prof.

Cristina Dorado, 1st sem., ABSTRACT The effect of molecular. The rate of diffusion is inversely proportional to resistance, distance traveled down a concentration gradient and the weight of the molecule.

How Does Molecular Weight Affect the Rate of Diffusion?

The molecular weight of a substance is the total weight of all atoms present in the compound. In TablePotassium permanganate holding the lowest molecular weight had an mean rate of diffusion of mm/min.

And Methylene Blue with the highest molecular weight had an mean rate of diffusion of mm/min. The Effect of Varying Molecular Weights on the Rate of Diffusion Essay Sample. The effect of molecular weight on the rate of diffusion was verified by the 2 tests: the glass tube setup and the water agar-gel setup.

The Effect of Varying Molecular Weights on the Rate of Diffusion Essay Sample The consequence of molecular weight on the rate of diffusion was verified by the 2 trials: the glass tubing apparatus and the H2O agar-gel apparatus.

The molecular weights of the substances are g/mole, g/mole and g/mole, respectively. KMnO4 is a purple substance, K2Cr2O7 is yellow and Methylene Blue has its color in its name.
